Description
Summary:Radio spectrum, as the physical support for wireless communication, both for fixed applications and especially for mobile broadband, is becoming an extremely strategic, valued, and demanded resource. [...]technologies and techniques enabling a more flexible access for service providers and clients and a more efficient and effective usage are needed. Cognitive radio takes a more active approach, making the devices responsible of efficient spectrum utilization by sensing spectrum usage and adjusting transmission parameters to accommodate communications in unused resources. [...]regulatory frameworks like the recent Licensed Shared Access (LSA) may play a crucial role in helping mobile networks operators to make a more efficient usage of the scarce bandwidth resources.
